The aerodynamic characteristics of flying insects were studied making use of the small low-turbulence wind tunnel and the morphological characteristics of insects were studied making use of the scanning electron microscope. The results obtained are summerized as follows ;1. The displacement of insect wing and velocity fluctuation generated by insect flight were simultaneously measured, and the flapping frequencies of many insects were decided.2. The flapping frequency of the insect is proportional to the -1/6th power of the mass of the insect itself. The proportional constant in the relation was decided.3. The parameters provided a description of the morphology of a flapping insect were measured. The Valensi number shows good arrangement of flying insects.4. The dragonfly repeats gliding and powered flight in usual flight. Dragonflies are versatile fliers, capable of adjusting their wing beat pattern to suit widely different manoeuvres.5. The cross section of the dragonfly costa varies in shape and size corresponding to the location of wing. There are remarkable irregularities in the wing.6. The number of vertices in the space morphology of the dragonfly, Sympetrum infuscatum, is distributed in n=6 and n=5.7. The costal vein of the dragonfly, Sympetrum infuscatum, is discontinued at the nodus.

利用小型低湍流风洞对飞行昆虫的气动特性进行了研究，并利用扫描电子显微镜研究了昆虫的形态特征。研究结果总结如下：1.同时测量了昆虫翅膀的位移和昆虫飞行时产生的速度波动，确定了多种昆虫的拍打频率。昆虫的拍打频率与昆虫本身质量的-1/6次方成正比。确定了该关系式中的比例常数。测量了描述扑动昆虫形态的参数。瓦伦西数显示飞虫排列良好。蜻蜓在平时的飞行中重复滑翔和动力飞行。蜻蜓是多才多艺的飞行员，能够调整它们的翅膀跳动模式，以适应广泛不同的动作。蜻蜓科斯塔的横截面形状和大小与翅膀的位置相对应。机翼有明显的不规则性。凤头蜻蜓的空间形态顶点数分别为n=6和n=5.7。蜻蜓的肋静脉在结节处中断。
